The 1985 Saab 900 sits squarely in the era when Saab’s distinctive hatchback and turbocharged personality had already earned a loyal following among drivers who wanted something more technical and individual than the usual compact European sedan. Its front-drive layout, upright glass, and strong enthusiast identity make tire choice especially important to both appearance and road manners. The 1985 Saab 900 uses 15-inch radial fitments, with 175/70R15, 185/65R15, and 195/60R15 appearing across the model range. Available choices include blackwall, redline, wide whitewall, and raised white letter treatments depending on size. The right selection starts with the exact sub-model, then moves to the look, series, and driving use you want.
Which Tire Size Is Right for The 1985 Saab 900
The 1985 Saab 900 uses three primary tire sizes, and the correct one depends on the exact sub-model. All three are radial tires for 15-inch wheels, so the key first step is confirming whether the car is a Base, S, Turbo, or SPG Turbo configuration. Once the right size is identified, the decision shifts to sidewall style, tire series, and whether you want a more traditional period-style look or a more modern radial presentation.
185/65R15 is a metric radial size in which 185 is the nominal section width in millimeters, 65 is the aspect ratio, R indicates radial construction, and 15 is the wheel diameter in inches. On the 1985 Saab 900, this size serves as one of the core fitments and suits owners who want to stay with the vehicle’s established 15-inch radial format. Available choices include BFGoodrich Silvertown Radial options with redline or 1.75-inch whitewall styling. It is a useful size for buyers balancing proper sub-model fitment with a restoration-oriented sidewall treatment.
175/70R15 is a metric radial size with a 175-millimeter nominal section width, a 70-series profile, radial construction, and a 15-inch rim diameter. On the 1985 Saab 900, this size appears on specific sub-model applications rather than across the full range, so it should be matched carefully to the car’s actual configuration. Product choices include blackwall radials from Avon in the CR6ZZ series and Vredestein in the Sprint Classic series. This size is worth evaluating when maintaining the correct fitment approach for an S model using the narrower radial specification.
195/60R15 is a metric radial size where 195 gives the nominal section width in millimeters, 60 identifies the aspect ratio, R denotes radial construction, and 15 marks the wheel diameter. For the 1985 Saab 900, it is associated with the sportier end of the range and gives buyers the broadest product spread among the available primary sizes. Choices include blackwall, redline, wide whitewall, and raised white letter sidewalls across BFGoodrich and Michelin offerings. This size deserves close attention on Turbo and SPG Turbo applications where exact fitment and intended appearance both matter.
Sub-model fitment matters on the 1985 Saab 900 because tire size is not the same across the full lineup. Every version uses a 15-inch radial, but the exact size changes by model, so confirming the badge and wheel setup is the first step before comparing products.

1985 Saab 900 Base
The 1985 Saab 900 Base uses the 185/65R15 radial size. That keeps selection fairly straightforward, with the main choice centered on whether a redline or wide whitewall presentation better suits the car’s intended look and use.
The 1985 Saab 900 S can use either 175/70R15 or 185/65R15, so this is one of the versions where checking the actual wheel and tire setup matters most. Tire selection starts with confirming which of those two sizes is already on the car or which wheel configuration it currently carries.
The 1985 Saab 900 SPG Turbo uses the 195/60R15 radial size. That opens up the widest visible range of sidewall treatments in this application, making it easier to choose between a more understated blackwall look and a more vintage-inspired presentation.
The 1985 Saab 900 Turbo can use either 185/65R15 or 195/60R15 depending on its exact setup. Choosing tires for this model begins with confirming the mounted size and wheel width, then narrowing the options by sidewall style and tire series.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Common 1985 Saab 900 tire questions usually come down to the right sub-model size, 15-inch rim fitment, radial tire choices, and how to balance appearance with road use. These answers focus on the actual sizes used across the 900 lineup and what to verify before installation.
Tire Size & Fitment
What tire size fits a 1985 Saab 900?
The 1985 Saab 900 uses three primary radial tire sizes: 175/70R15, 185/65R15, and 195/60R15. The exact size depends on the sub-model. Base models use 185/65R15, SPG Turbo models use 195/60R15, while S and Turbo models can use more than one size depending on configuration.
That means the first step is identifying the exact sub-model and then confirming what is actually on the car today. A previous owner may have changed wheels or tires, and the S and Turbo especially deserve a close look at the current sidewall markings before selecting a replacement.
What size rim does a 1985 Saab 900 use?
The 1985 Saab 900 uses 15-inch rims across its listed tire fitments. All three primary sizes for this model range, 175/70R15, 185/65R15, and 195/60R15, are built around the same 15-inch rim diameter even though their section widths and profiles differ.
Rim diameter is only part of the fitment picture, so it still helps to verify wheel width before choosing among available tires. Product specifications in these sizes show different approved rim-width ranges, and that becomes especially important if the car has replacement wheels or a model-specific performance setup.
Why does the 1985 Saab 900 have more than one tire size?
More than one tire size appears on the 1985 Saab 900 because the model range includes different sub-model applications. The Base, S, Turbo, and SPG Turbo do not all share the same tire specification, and some versions of the S and Turbo can be found with two primary size fitments.
That variation makes sub-model identification more important than simply ordering by year and make alone. Once the exact model is confirmed, check the size on the sidewall and compare it to the wheel currently on the car so the replacement matches both the vehicle configuration and the installed rim.
Choosing the Right Tire
What should I consider when choosing a tire for a 1985 Saab 900?
Start with the correct primary size for the car: 175/70R15, 185/65R15, or 195/60R15 depending on sub-model. From there, compare the available tire series, sidewall style, and approved rim-width range. The 1985 Saab 900 is a radial-fitment car, so construction choice is straightforward compared with many earlier classics.
After size is confirmed, the real decision is how you want the car to look and be used. A blackwall can suit a more understated or contemporary presentation, while redline, wide whitewall, or raised white letter options can shift the car toward a stronger period-style statement.
What sidewall styles are available for 1985 Saab 900 tires?
Sidewall choices for the 1985 Saab 900 include blackwall, redline, wide whitewall, and raised white letter depending on the tire size. Blackwall appears in 175/70R15 and 195/60R15 options, while 185/65R15 is available with redline and wide whitewall styling through BFGoodrich Silvertown Radial offerings.
The right sidewall is mostly an appearance decision once the correct fitment has been established. It helps to think about whether the car is being kept close to an understated European look, given a stronger 1980s performance character, or finished with a more customized restoration-oriented visual treatment.
What brands offer tires for the 1985 Saab 900?
Tires for the 1985 Saab 900 are available from BFGoodrich, Avon, Vredestein, and Michelin across the listed fitments. Brand availability depends on the size. BFGoodrich appears in 185/65R15 and 195/60R15, while Avon and Vredestein cover 175/70R15, and Michelin appears in 195/60R15.
Brand selection should follow fitment first, then tire character and presentation. Some choices lean more toward traditional styling, while others present a more modern blackwall appearance. Comparing the available series within the correct size is more useful than trying to treat every brand as interchangeable across the full 900 lineup.
Restoration & Appearance
Which tire should I choose for a period-style 1985 Saab 900?
A period-style 1985 Saab 900 tire choice starts with the correct sub-model size, since the car may use 175/70R15, 185/65R15, or 195/60R15. Once size is settled, look at sidewall presentation and tire series. Redline, wide whitewall, raised white letter, and blackwall options all create a different visual impression.
The best match depends on whether the goal is a restrained European look, a sport-oriented 1980s feel, or a more customized restoration direction. When exact originality matters, it is worth checking marque references or period photos so the finished appearance aligns with the way the specific car is being restored.
How does tire construction affect the appearance of a restored 1985 Saab 900?
On the 1985 Saab 900, construction is less of an appearance divide than it is on older bias-ply-era vehicles because the primary fitments are already radial. The bigger visual change comes from sidewall treatment and tire series. A blackwall reads cleaner and more understated, while redline, wide whitewall, or raised white letter styling stands out more strongly.
That makes restoration appearance more about presentation than about choosing between bias-ply and radial construction. Tire size still needs to stay correct for the sub-model, but once that is established, the sidewall style becomes one of the easiest ways to shape the car’s final stance and era-specific character.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1985 Saab 900?
Yes, modifications can affect tire fitment on a 1985 Saab 900 even when the replacement tire is one of the correct listed sizes. Aftermarket wheels, changes in wheel width, suspension alterations, or body modifications can change clearance at the fender, inner wheelhouse, or steering components.
A car that has been lowered or fitted with non-original wheels deserves a closer check before installing replacement tires. Verifying actual wheel width, confirming the mounted size on the car, and checking for clearance through full steering travel are smart steps before settling on 175/70R15, 185/65R15, or 195/60R15.
What should I inspect before driving a 1985 Saab 900 on new tires?
Before driving a 1985 Saab 900 on new tires, inspect the wheels for damage, confirm that all four tires match the intended size for the sub-model, and set inflation pressure correctly for the tire and vehicle setup. It also helps to check alignment-related wear patterns on the old tires before removal.
Roadworthiness is not only about the new tires themselves. Wheel hardware, suspension condition, and steering components should be in sound order so the car can take full advantage of the fresh rubber. A short test drive followed by another visual check can reveal rubbing, vibration, or air-loss issues early.
How should tires on a collector 1985 Saab 900 be maintained?
Tires on a collector 1985 Saab 900 should be kept properly inflated, inspected regularly for cracking, bulges, cuts, and uneven wear, and protected from long idle periods on the same contact patch. Cars that are driven infrequently can show age-related tire issues even when tread depth still looks acceptable.
Storage conditions matter as much as mileage on a low-use 900. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve the tires between drives. It is also wise to recheck pressure and look for flat spotting or air loss before any longer outing.
